Solving Number problems are an important research field of mathematics. In mathematical competitions, problems of basic number theory occur frequently. These problems use slight knowledge and have many variations. They are flexible and diverse. The number problems are much related to the human life. Number problems used to solving the particular value by using the remaining values.

Solving number Example problems:

1) Twice the larger of the 2 numbers is 3 more than 5 times the smaller and the sum of four times the larger and three times the smaller is 51. What are the numbers?

The point is in the solving the number problem, not in the relative reality of the problem. That said, how do you solve this number problem? The best first step is to start labeling:

The larger number: x the smaller number: y

Twice the larger: 2x three more than five times the smaller: 5y + 3 relationship between (”is”): 2x = 5y + 3
